A doctor or nurse who specializes in chemotherapy port placement will perform the minor surgical procedure, usually on an outpatient basis, says Cancer.net. The port is placed just under the skin and connects to a catheter, or tube, inserted into a large blood vessel.
Ports are used in the long-term treatment of cancer, allowing ready access to the blood vessel to administer chemotherapy drugs, medications and to draw blood, according to the American Cancer Society webpage. They are usually located just under the collar bone, states the Veins For Life website, but can be placed at another location if needed. Ports are removed by a nurse or doctor when all chemotherapy treatment has been completed, says BreastCancer.org.
